The PI6C2501AWE is an integrated and highly efficient Clock Synthesizer and Multiplier composed of the Clock Synthesizer and the frequency doubler. It is designed for a wide variety of applications, such as in consumer electronics, telecommunications, wireless, networking, and any other application where an accurate clock source is needed. This one chip solution packs a number of features into a small package, making it an ideal option for high-performance and cost-effective applications.

The PI6C2501AWE can generate frequencies up to 400 MHz with a maximum output drive strength of 16mA. It features a low power consumption, shutdown mode and built-in self-test. It also supports high accuracy and stability, allowing the user to have a reliable clock source. The output can be disabled and enabled on the fly, allowing users to adjust the parameters of their clock as needed. The on-chip voltage regulator also makes it easier to set up and maintain stable power supply.

The PI6C2501AWE offers multi-channel frequency synthesis, enabling the user to generate multiple frequencies from the same device. It also provides multiple feedback types, allowing the user to select the optimal feedback configuration for a given application. The output frequencies can be divided by a power of two, allowing for flexible up or down conversion of the output frequency.

Working principle: The PI6C2501AWE works by using a Phase-Locked Loop (PLL) circuit to synthesize and multiply a frequency. The PLL consists of a Voltage Controlled Oscillator (VCO), which is used to generate the output frequency, a Low-Pass Filter (LPF), which helps to reduce noise and jitter, a Phase Detector, which provides a comparison of the frequency, and a Charge Pump, which drives the VCO control voltage. The VCO output is then multiplied and divided by the user-specified factors to produce the desired output frequency.

The user can make any number of settings in the PLL circuit to adjust the output frequency of the PLL. These settings include the Input Frequency Scale, which determines the amount of frequency multiplication, the Output Divide Ratio, which determines the amount of frequency division, and the Pole Gain Constant, which determines the stability of the output voltage.

The PI6C2501AWE offers logic outputs for each output frequency and a single input for power. It also has a low power mode and a low operating voltage. By using the high accuracy and stability of the PI6C2501AWE, users can rely on its clock source for a variety of applications.
